RE: Valuable experience about industry | 3rd | Water Treatment | 5% to SL-Charity
I remembered that my A/L time. Some of the things that are said feel a little familiar. Using clean water is a very valuable thing for anyone. It may be helpful for us to be aware of that someday. We hope you continue to tell us valuable things like this. Thank you. 👍
We have to use different methord according water quality. I hope to share all of thing that I know..
Here we are waiting... 🙃
